When i am running this script like ./script start, script able to find proxy settings and passing the proxy settings. But while running with service script start not able to find proxy settings. Did i miss anything to load environment variables while running script with service?

From man service:
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working directory set to /.
So when you try to run a service script, only several env variables like TERM, LANG remains, your http_proxy and https_proxy is discarded. To use environment variables you need, you could define them in file /etc/default/yourservice with:
http_proxy=http://yourproxy.com
https_proxy=http://yourproxy.com
and source it in the beginning of your script:
[ -f /etc/default/yourservice ] && . /etc/default/yourservice
